Assessing the importance of American eel (Anguilla rostrata) restoration to freshwater mussel populations in the Susquehanna River

The eastern elliptio mussel (Elliptio complanata) is a freshwater mussel that is abundant in many eastern streams and rivers along the Atlantic coast. Mussels provide important functions in stream ecosystems that help improve water quality such as filtration of algae, sediment, and micronutrients from the water column. Larval stage (glochidia) eastern elliptio must parasitize a host fish...

Assessment of the immune status of wild and laboratory-maintained smallmouth bass

Deaths of young-of-year smallmouth bass in the Chesapeake Bay drainage has been noted since 2005. Studies of affected fish have found bacterial, viral and parasitic infections. Mixed infections suggest these fish are immunosuppressed. Understanding the role of specific pathogens and environmental factors that contribute to their presence is important but equally important is the understanding of...

Statistical Research for the USGS - Amphibian Research and Monitoring Initiative

The Challenge: Since its inception in 2002 the USGS Amphibian Research and Monitoring Initiative (ARMI) has taken the lead in monitoring amphibian populations on Department of Interior lands. ARMI scientists work on a broad spectrum of species and management issues to address the core causes of amphibian declines. In many cases, research requires complex study designs and innovative methods. A key...

Assessing Amphibian Disease Risk in the Northeast

Disease in amphibian populations can have a range of effects, from devastating declines following introduction of a novel pathogen to recurring breakout events on a landscape. Elucidating mechanisms underlying the effects of diseases on amphibian populations is crucial to help managers make appropriate decisions to achieve management goals for amphibians.

Amphibian Research and Monitoring Initiative (ARMI): Understanding Amphibian Populations in the Northeastern United States

Currently, 90 amphibian species are recognized in the Northeast, including 59 species in the Order Caudata (salamanders) and 31 species in the Order Anura (frogs and toads). Almost half of the amphibians in the Northeast are salamanders within the family Plethodontidae. Amphibians are found in all physiographic regions of the Northeast, from sea level to the heights of the Appalachian, Adirondack...

Development of a Multimetric Index for Integrated Assessment of Salt Marsh Condition in the Northeast Coastal and Barrier Network

Salt marsh ecosystems along all US coastlines have been altered, degraded, and destroyed by human activities, including ditching and drainage of the marsh platform, tidal restrictions, discharge of pollutants, and introduction of invasive species. The National Park Service conducts long-term monitoring of salt marsh vegetation and nekton (fish and free-swimming crustaceans) to provide information...
